Abstract:
Objective:To compare the incidence of postoperative complications of single- and multiple-perforator flaps, to provide reference for future clinical decision.Methods:Literatures on the comparison of postoperative complications of single- and multiple-perforator flaps at home and abroad from January 1995 to December 2020 were searched in PubMed, Cochrane Library, Embase, Wanfang, CNKI, VIP database. The literatures were screened and extracted according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.3 software.Results:8 studies were included, including 1 008 flaps. There were 535(53%) single-perforator flaps, 473(47%) multiple-perforator flaps. Compared with multiple-perforator flaps, single-perforator flaps had a higher rate of venous crisis ( OR=2.29, 95% CI: 1.25-4.21, Z=2.67, P=0.008) and a higher rate of fat necrosis ( OR=2.04, 95% CI: 1.02-4.10, Z=2.10, P=0.040), the total necrosis rate of flaps was higher ( OR=2.71, 95% CI: 1.26-5.86, Z=2.54, P=0.010), and the differences were statistically significant. There were no significant differences in the incidence of arterial crisis ( OR=1.18, 95% CI: 0.48-2.90, Z=0.37, P=0.710) and partial necrosis of flaps ( OR=1.20, 95% CI: 0.61-2.36, Z=0.52, P=0.600). Conclusion:Compared with multiple-perforator flap, single-perforator flap may have higher incidence of venous crisis, fat necrosis and complete necrosis.
